I had a problem in understanding the concept of heteroatoms, which is described as elements replacing hydrogen in an organic compound.
see in a organic compound, say methane, we replace one hydrogen with Cl and it becomes ch3cl and Cl is a heteroatom.
now lets take the case of CHO. (Aldehyde group) why is it also called a heteroatom ? see because in an organic compound say - propane we add aldehyde group ,this is happening -
CH3CH2CH3, CHO. - CH3CH2CHO
so isint only O replacing two hydrogen atoms? so shouldn't O be the heteroatom but no we call the whole group the heteroatom,
for which the only explanation I can think of is, for say to make propanal,
ethyl + CHO group,
that is CH3CH2 + CHO
that makes sense as from ethane, we are removing one hydrogen and the whole CHO is replacing it.is this right?
Sir, please explain where am I going wrong? I hate concepts not being clear.
In organic chemistry , a heteroatom is any atom that is not carbon or hydrogen . Usually, the term is used to indicate that non-carbon atoms have replaced carbon(not a hydrogen!!!) in the backbone of the molecular structure. Typical heteroatoms are nitrogen, oxygen , sulfur, phosphorus, chlorine, bromine, and iodine.
